Little-known battery trick
If you’re out of AA batteries, did you know you can use a smaller AAA battery by folding up a small bit of tin foil and inserting it on one of the ends? It totally works since AA and AAA batteries carry the same amount of voltage.
How do you connect AAA batteries in series?
To connect a group of batteries in series you connect the negative terminal of one battery to the positive terminal of another and so on until all batteries are connected, you would then connect a link/cable to the negative terminal of the first battery in your string of batteries to your application, then another
How long do laser batteries take to charge?

How long can a laser pointer stay on?
The actual answer: About 1/4–3 seconds, depending on what laser pointer. Lasers are rated for safety assuming you’ll avoid looking at them, so anything more than one second “blink reflex” time is considered potentially dangerous.
What do you use AAA batteries for?
Also known as “triple A”, AAA batteries are the second most popular kind of battery. They are used for small toys, thermometers, and calculators. Triple A batteries are often used for small electronic devices such as TV remote controls, kitchen timers, graphing calculators, and bathroom scales.
What’s the difference between AA and AAA batteries?
AA and AAA are battery designations that are used to indicate the size and potential charge capacity of certain batteries. The most significant difference between the two, is their size. AAA batteries are smaller compared to AA. This is important, as battery operated devices often use only one specific size.
What does AAA stand for on a battery?
triple-A battery
The AAA battery (or triple-A battery) is a standard size of dry cell battery. One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by IEC as R03, by ANSI C18.
What kind of batteries go in laser for gun?

Can you drill a AAA battery?
Use a drill with a long bit and screw it into the end of the battery. Once the bit is secure in the battery, pull it out. It may take some maneuvering, but the battery should come out with it.This works on both alkaline and acidic batteries.
How do you hook up a battery pack?
To join batteries in parallel, use a jumper wire to connect both the positive terminals, and another jumper wire to connect both the negative terminals of both batteries to each other. Negative to negative and positive to positive. You CAN connect your load to ONE of the batteries, and it will drain both equally.
Which side is positive and negative on a battery?
Each battery has two metal terminals. One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-).
Which side of battery goes against spring?
Batteries have a positive terminal and a negative terminal. The negative side of the battery should be touching the spring when installing it. The purpose of that spring is to ensure that you have the correct polarity when installing the batteries, and it also helps with consistency in knowing which way they go.
A button battery works the exact same way as AA and AAA ones. They have a round diameter, and two electrodes of complementary metals. A separator that technicians call electrolyte sits between them, and controls the flow of ions that make the electricity.
Which side of the battery goes on first?
Positive
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
